The water level in the Dead Sea get, a noticeable decline, leaving behind it thousands of holes, where there are currently nearly 3,000 hole on the occupied Palestinian side and hundreds of holes on the Jordanian side.
This sudden severe increase in the frequency of these holes, at a time the sea wa contains only 40 hole in 1990. The drought of the Dead Sea began at the beginning of the sixties due to excessive consumption of the Jordan River, which is the main river pours into it, and because of the many evaporation holes on its shores which are used to extract the precious metals.
It is expected that the lake, the most natural salinity and below the Earth's surface lake , dries out in the full year 2050.
There are two contending hypotheses about the origin of the low elevation of the Dead Sea. The older hypothesis is that it lies in a true rift zone, an extension of the Red Sea Rift, or even of the Great Rift Valley of eastern Africa. A more recent hypothesis is that the Dead Sea basin is a consequence of a "step-over" discontinuity along the Dead Sea Transform, creating an extension of the crust with consequent subsidence.
